Very low in energy and not sure why.

Hi, I have pcod. I feel low in energy, my insulin resistance is there. But these days I feel very slow, wanting to be active but not able to. Mind is mostly anxious and body slow. A friend asked me to get checked my vitamins and minerals which are necessary in my condition or what should I do.I am not liking the way I am being because I like to feel active and keep thriving but these days too low specially after periods from last week. Is it normal? I feel overwhelming and lethargic. Kindly help me what supplements are must for me? Any tests I should take surely? I heard about ovasitol but no idea if it should be without prescription or with and if available in India? Doctors please help :( I want to feel active and energetic normally. People around me Dont understand that it's not my excuse its the situation I am in.I feel so bloated and demotivated.
